1、農作物秸稈量大，覆蓋面廣，燃料來源充足。2、秸稈含硫量很低。國際能源機構的有關研究表明，秸稈的平均含硫量只有千分之3.8，而煤的平均含硫量約達百分之一。且低溫燃燒產生的氮氧化物較少，所以除塵后的煙氣不進行脫硫，煙氣可直接通過煙囪排入大氣。丹麥等國家的運行試驗表明秸稈鍋爐經除塵后的煙氣不加其他凈化措施完全能夠滿足環保要求。所以秸稈發電不僅具有較好的經濟效益，還有良好的生態效益和社會效益。3、各類作物秸稈發熱量略有區別，但經測定，秸稈熱值約為15000KJ/Kg，相當于標準煤的50%。其中麥秸稈、玉米秸稈的發熱量在農作物秸稈中為最小，低位發熱量也有14.4MJ/kg，相當0.492kg標準煤。使用秸稈發電，可降低煤炭消耗。

　　1. The amount of crop straw is large, the coverage is wide, and the fuel source is abundant. 2. Straw has a very low sulfur content. According to research by the International Energy Agency, the average sulfur content of straw is only 3.8% per thousand, while the average sulfur content of coal is about 1%. And the nitrogen oxides produced by low-temperature combustion are relatively small, so the flue gas after dust removal is not desulfurized, and the flue gas can be directly discharged into the atmosphere through the chimney. The operational tests in countries such as Denmark have shown that the flue gas from straw boilers after dust removal can fully meet environmental protection requirements without other purification measures. So straw power generation not only has good economic benefits, but also good ecological and social benefits. 3. The calorific value of straw varies slightly among different crops, but according to measurements, the calorific value of straw is about 15000KJ/Kg, which is equivalent to 50% of standard coal. The calorific value of wheat straw and corn straw is the smallest among crop straw, with a low calorific value of 14.4MJ/kg, equivalent to 0.492kg of standard coal. Using straw for power generation can reduce coal consumption.

　　4、秸稈通常含有3%~5%的灰分，這種灰以鍋爐飛灰和灰渣/爐底灰的形式被收集，含有豐富的營養成分如鉀、鎂、磷和鈣，可用作高效農業肥料。

　　4. Straw typically contains 3% to 5% ash, which is collected in the form of boiler fly ash and ash/furnace bottom ash. It is rich in nutrients such as potassium, magnesium, phosphorus, and calcium and can be used as an efficient agricultural fertilizer.

　　?5、作為燃料，煤炭開采具有一定的危險性，特別是礦井開采，管理難度大。農作物秸稈與其相比，則危險性小，易管理，且屬于廢棄物利用。

　　As a fuel, coal mining has certain risks, especially in mine mining, which is difficult to manage. Compared with it, crop straw is less dangerous, easier to manage, and belongs to waste utilization.
